Brilliantly handled art-style, super sleek gameplay, and perseverance-encouraging music. As challenging as this game was, it was insanely fun. The game flowed nicely and had very well-designed stages.
I had some minor problems concerning my understanding of what to do. The "way to go" was unclear to me for quite a few levels. It was not that big of deal as I understand the concept of trial and error, but I could have done better with some better indication (not trying to be air-headed, I may just not be skilled enough to examine the levels fast enough).
All in all, great game!
PS: No hate, but the canons frustrate me lol (esp. Act 2-8). Nothing wrong with the canons, there's just always that one mechanic, in these kinds of games, that becomes the bane of my existence. Also, omg, that last level was rough.
